Description

Technical Field

[0001] The present invention relates to the technical field of food inspection, and particularly to an efficient food inspection analysis reagent adding device and a using method thereof. Background Art

[0002] Food inspection is a discipline that studies and evaluates the quality of food and its changes. Food inspection is based on some basic theories and various technologies of physics, chemistry, and biochemistry, and in accordance with the formulated technical standards (such as international and national food hygiene / safety standards), the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products is inspected to ensure that the product quality is qualified.

[0003] Chinese Patent with publication number CN118566446A discloses an efficient food inspection analysis reagent adding device, including an adding frame, and further including an adding mechanism arranged on the surface of the adding frame. The adding mechanism includes an adding component, a continuous component, a liquid adding component, and a friction component. The adding component is arranged inside the adding frame, the continuous component is arranged on the surface of the adding frame, the liquid adding component is arranged below the adding component, and the friction component is arranged above the adding frame; it is beneficial to make the test tube rack and the iron connecting rod move alternately and intermittently, so as to realize the intermittence of adding analysis reagents, improve the efficiency of adding food inspection analysis reagents, and is beneficial to adding analysis reagents into the syringe, ensuring that the amount of analysis reagents in multiple syringes is the same and ensuring that the amount of analysis reagents added each time is the same. However, when this solution is actually used, there are still the following deficiencies: In the precise process of food inspection analysis, a crucial step is to accurately add analysis reagents into food test tubes for subsequent chemical reactions and component analysis. However, this step is often preceded by a crucial but easily overlooked link - the preparation of analysis reagents. The preparation process not only requires precise measurement of the proportions of various raw materials to ensure the efficacy and accuracy of the reagents, but also involves how to fully mix these raw materials evenly so that they can quickly and effectively play their roles after being added to food test tubes. Traditionally, this mixing process relies on manual operation, that is, the experimenter needs to hold the test tube or container and shake the raw materials evenly by hand. However, this manual shaking method is not only inefficient, consuming a large amount of time and physical strength, but also often difficult to achieve the ideal mixing uniformity. Due to the limitations and inconsistencies of manual operation, the distribution of each component in the reagent may be uneven, thereby affecting the accuracy and reliability of the test results.

[0015] A method for using a high-efficiency food inspection and analysis reagent adding device comprises the following steps: Step 1: The staff adds the raw materials of the analytical reagent into the reagent barrel in a certain amount, turns on the drive motor, and prepares to mix the raw materials.

[0016] Step 2: The driving motor drives the worm to rotate, and the worm meshes with the worm wheel, driving the worm wheel and the shaft to rotate. The eccentric wheels at both ends of the shaft drive the two fixed plates to slide back and forth through the opening, and the connecting plate drives the driving rack to slide and meshes with the transmission gear, driving the fixed pipe to rotate back and forth, and the connecting pipe and the reagent barrel rotate back and forth with the fixed pipe. At the same time, the reagent barrel reciprocates vertically along the corrugated guide groove through the guide rod to ensure that the raw materials are fully and quickly mixed.

[0017] Step 3: After the reagents are mixed, place the test tube containing the food solvent in the placement port of the placement plate, turn on the electric push rod, drive the addition tube to slide along the guide port to the top of the test tube through the guide plate, turn on the addition pump, draw the reagent to the addition pump through the connecting tube, the fixed tube and the liquid supply tube, and then add it to the test tube quantitatively along the guide tube and the addition tube. When the addition tube moves downward, the transmission rod pushes the receiving bucket to rotate to an inclined state to avoid affecting the downward movement of the addition tube. After the addition is completed, the electric push rod drives the addition tube to move up and reset, and the transmission rod pulls the receiving bucket to rotate to a horizontal state to receive the droplets at the port of the addition tube to avoid contaminating the inspection table.

[0018] Step 4: Turn on the drive motor again, and drive the transmission shaft to rotate through the synchronous belt and the driven wheel. The driving bevel gear meshes with the driven bevel gear, driving the driven bevel gear and the eccentric wheel 2 to rotate. The eccentric wheel 2 pushes the transmission frame. With the cooperation of the spring, the transmission plate and the support frame slide back and forth along the guide frame, so that the test tube reciprocates in the horizontal direction to achieve vibration and ensure rapid mixing of the reagent and the solvent.

[0019] Step 5: After the inspection is completed, remove the placement plate from the support frame, move the positioning rod out of the positioning port, and then the test tubes can be taken out at one time.

[0020] The present invention has the following beneficial effects: 1. By setting a linkage component and a support component, the worm is driven to rotate by a driving motor, and the worm is meshed with the worm wheel to drive the shaft to rotate. The eccentric wheels at both ends of the shaft drive the fixed plate to slide back and forth through the opening, and then drive the fixed tube to rotate back and forth through the connecting plate and the driving rack. At the same time, the reagent barrel rotates with the fixed tube and slides in the corrugated guide groove through the guide rod, so that the reagent barrel can reciprocate in the vertical direction. This composite motion mode of rotation and movement ensures that the raw materials in the reagent barrel can be fully and quickly mixed, improves the mixing efficiency, and provides accurate analytical reagents for subsequent addition inspections; 2. By setting up the linkage component and the connection component, after the reagent addition is completed, by turning on the drive motor again, the synchronous belt and the driven wheel are used to drive the transmission shaft to rotate, thereby driving the bevel gear to mesh with the driven bevel gear, driving the eccentric wheel two to rotate, the eccentric wheel two pushes the transmission frame, and with the cooperation of the spring, the transmission plate and the support frame slide reciprocally along the guide frame, enabling the test tube on the placement plate to move horizontally in a reciprocating manner to achieve vibration. This vibration method effectively promotes the rapid mixing of the reagent and the solvent in the test tube, shortens the mixing time, improves the inspection efficiency, and ensures the accuracy of the inspection results; 3. By setting up the addition tube and the anti-pollution structure, during the reagent addition process, the electric push rod drives the addition tube to slide down along the guide port, and the reagent in the reagent barrel is pumped into the addition pump through the addition pump, and then quantitatively added to the test tube along the conduit and the addition tube. When the addition tube moves down, the transmission rod pushes the receiving hopper to rotate to an inclined state to avoid affecting the normal downward movement of the addition tube. After the addition is completed, when the electric push rod drives the addition tube to move up and reset, the transmission rod pulls the receiving hopper to rotate to a horizontal state and is located directly below the addition tube to receive the liquid droplets at the port of the addition tube. Since the backing plate in the receiving hopper is made of a water-absorbing material, it can effectively absorb the liquid droplets and avoid the liquid droplets from polluting the inspection table. This anti-pollution structure not only keeps the inspection environment clean but also improves the accuracy and reliability of the inspection. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed ring plate 4 is fixedly installed on the top surface of the inspection table 1 through a bracket. A reagent barrel 5 is arranged inside the fixed ring plate 4. A filling port is formed in the top surface of the reagent barrel 5. A support assembly is arranged between the reagent barrel 5 and the fixed ring plate 4. A connection assembly is arranged between the placement plate 2 and the inner bottom surface of the inspection table 1. A drive motor 8 is fixedly installed on the side surface of the inspection table 1. A linkage assembly is arranged between the output end of the drive motor 8 and the support assembly and the connection assembly. An adding pump 10 is arranged on the top surface of the inspection table 1. A plurality of adding pipes 11 corresponding to the placement openings 3 are arranged on the inner top surface of the inspection table 1. An anti-fouling structure is arranged between the adding pipes 11 and the inner top surface of the inspection table 1. A conduit 13 is arranged between the adding pipes 11 and the adding pump 10; During use, first, the staff can quantitatively add the raw materials of the analytical reagent into the reagent barrel 5 and turn on the driving motor 8. When the driving motor 8 is turned on, it can drive the support assembly to operate through the linkage assembly. When the support assembly operates, it can drive the reagent barrel 5 to move in the fixed ring plate 4, so as to fully mix the raw materials in the reagent barrel 5, and then conduct addition and inspection. After the analytical reagent is mixed, the staff can place the test tube containing the food solvent in the placement port 3 on the placement plate 2 and place the placement plate 2 through the connection assembly. After placement, the addition pump 10 can be turned on to quantitatively add the reagent in the reagent barrel 5 into the test tube along the addition tube 11 through the conduit 13. And after the addition is completed, under the action of the anti-fouling structure, the reagent at the port of the addition tube 11 will not drip, avoiding contamination. Subsequently, turning on the driving motor 8 again can drive the connection assembly and the placement plate 2 through the linkage assembly, so that the solvent in the test tube can be quickly mixed with the analytical reagent for inspection. After the inspection is completed, the test tube can be taken out.

[0024] The support assembly includes a corrugated guide groove 61 opened on the inner wall of the fixed ring plate 4, a guide rod 62 symmetrically and fixedly installed on the outer wall of the reagent barrel 5, and a communicating pipe 63 penetrating through the bottom surface of the reagent barrel 5. The guide rod 62 is slidably connected with the corrugated guide groove 61. The inner wall of the bracket is rotatably installed with a fixed pipe 64 through a connecting frame, and the fixed pipe 64 is slidably connected with the communicating pipe 63. A transmission gear 65 is sleeved on the outer wall of the fixed pipe 64. A rotary joint is arranged at the bottom end of the fixed pipe 64. A liquid supply pipe 66 is fixedly installed on the inner wall of the rotary joint, and one end of the liquid supply pipe 66 away from the rotary joint is communicated with the liquid inlet end of the addition pump 10. The liquid supply pipe 66 is arranged in an L shape; The linkage assembly can drive the fixed pipe 64 to rotate reciprocally through the transmission gear 65. At the same time, during the reciprocating rotation of the fixed pipe 64, the communicating pipe 63 is slidably connected with the fixed pipe 64. Therefore, the communicating pipe 63 and the reagent barrel 5 can rotate reciprocally with the fixed pipe 64. During the reciprocating rotation of the reagent barrel 5, the guide rod 62 on its outer wall can slide along the corrugated guide groove 61 on the inner wall of the fixed ring plate 4. Therefore, it can drive the reagent barrel 5 to move reciprocally in the vertical direction. Cooperating with the reciprocating rotation of the reagent barrel 5, it ensures that the raw materials in the reagent barrel 5 can be fully and quickly mixed evenly.

[0025] The connecting assembly includes a guide frame 71 fixedly mounted on the inner bottom surface of the inspection table 1, a transmission plate 72 slidably mounted on the inner wall of the guide frame 71, and a support frame 73 fixedly mounted on the top surface of the transmission plate 72. A spring 74 is symmetrically fixedly mounted between one end of the transmission plate 72 and the inner wall of the guide frame 71. A transmission frame 75 is fixedly mounted on the end of the transmission plate 72 away from the spring 74. A clearance opening 76 is provided at the end of the guide frame 71 away from the spring 74. Positioning openings 77 are provided at the four corners of the bottom surface of the support frame 73. Positioning rods 78 adapted to the positioning openings 77 are fixedly mounted at the four corners of the bottom surface of the placement plate 2. The linkage assembly can push the transmission frame 75. With the cooperation of the spring 74, the transmission plate 72 and the support frame 73 can slide back and forth along the guide frame 71, so that the test tube on the placement plate 2 can move back and forth in the horizontal direction to achieve vibration, ensuring that the reagents and solvents can be quickly mixed for testing. After the test is completed, the placement plate 2 can be removed from the support frame 73, and the positioning rod 78 can be moved out of the positioning port 77, so that the test tube can be taken out at one time, which is more convenient.

[0026] The linkage assembly includes a connecting plate 91 symmetrically slidably mounted on the top surface of the inspection table 1 through a support frame, a driving rack 92 fixedly mounted on the end of the connecting plate 91, and a fixed plate 93 fixedly mounted on the end of the connecting plate 91 away from the driving rack 92. The driving rack 92 is meshed with the transmission gear 65. The sides of the two fixed plates 93 are provided with through openings 94. The top surface of the inspection table 1 is rotatably mounted with a shaft 95 through a fixed frame, and both ends of the shaft 95 are fixedly mounted with eccentric wheels 96 adapted to the through openings 94. The outer wall of the shaft 95 is sleeved with a worm gear 97. A worm 98 is fixedly mounted on the output end of the drive motor 8, and the worm 98 is meshed with the worm gear 97. A transmission mechanism is provided between the drive motor 8 and the connecting assembly. The transmission mechanism includes a transmission shaft 99 rotatably mounted on the side of the inspection table 1 through a mounting frame, a driving bevel gear 910 fixedly mounted on the end of the transmission shaft 99, and an eccentric wheel 911 rotatably mounted on the inner top surface of the inspection table 1. The side surface of the transmission frame 75 is arranged in an arc shape corresponding to the eccentric wheel 911. The transmission shaft 99 and the output end of the driving motor 8 are connected through a driven wheel and a synchronous belt transmission. A driven bevel gear 912 is fixedly mounted on the top surface of the eccentric wheel 911, and the driven bevel gear 912 is meshed with the driving bevel gear 910. The eccentric wheel 911 passes through the clearance opening 76 and fits the side surface of the transmission frame 75. Turn on the drive motor 8. When the drive motor 8 is turned on, it can drive the worm 98 to rotate. The worm 98 meshes with the worm gear 97, and then can drive the worm gear 97 and the shaft rod 95 to rotate. When the shaft rod 95 rotates, the eccentric wheels one 96 at both ends thereof are symmetrically arranged. Therefore, when the two eccentric wheels one 96 rotate, they can drive the two fixing plates 93 to reciprocate slide through the through port 94 in sequence, thereby driving the drive rack 92 to slide through the connecting plate 91. The drive rack 92 meshes with the transmission gear 65, and then can drive the fixed tube 64 to reciprocate and rotate. At the same time, the drive motor 8 can drive the transmission shaft 99 to rotate through the synchronous belt and the driven wheel. The drive bevel gear 910 meshes with the driven bevel gear 912, and then can drive the driven bevel gear 912 and the eccentric wheel two 911 to rotate. During the rotation of the eccentric wheel two 911, it can push the transmission frame 75.

[0027] The anti-fouling structure includes a support plate 121 fixedly installed on the inner top surface of the inspection table 1, a guiding port 122 opened on the side surface of the support plate 121, and a guiding plate 123 slidably installed on the inner wall of the guiding port 122. The end of the guiding plate 123 is fixedly connected to the outer wall of the adding tube 11. The bottom end of the support plate 121 is hinged with a receiving hopper 124. A transmission rod 125 is hinged at the side position of the top surface of the receiving hopper 124, and the end of the transmission rod 125 away from the receiving hopper 124 is hinged to the outer wall of the adding tube 11. A cushion plate 126 is arranged on the inner bottom surface of the receiving hopper 124. An electric push rod 127 connected to the guiding plate 123 is fixedly installed on the inner top surface of the inspection table 1; After the reagents in the reagent barrel 5 are mixed and the test tubes are placed, the electric push rod 127 can be turned on to drive several adding tubes 11 to slide along the guiding port 122 through the guiding plate 123, so that the adding tubes 11 move downward. Then, the adding pump 10 is turned on to pump the reagents in the reagent barrel 5 into the adding pump 10 through the connecting pipe 63, the fixed tube 64 and the liquid supply pipe 66, and the reagents can be quantitatively added into the test tubes along the conduit 13 and the adding tubes 11. During the downward movement of the adding tubes 11, the receiving hopper 124 can be pushed through the transmission rod 125, so that the receiving hopper 124 rotates from the horizontal state to the inclined state, avoiding affecting the normal downward movement of the adding tubes 11. As the reagent addition is completed, during the process of the electric push rod 127 driving the adding tubes 11 to move upward and reset, the receiving hopper 124 can be pulled through the transmission rod 125, so that the receiving hopper 124 rotates to the horizontal state and is located directly below the adding tubes 11. The liquid drops at the ports of the adding tubes 11 can drip onto the cushion plate 126 in the receiving hopper 124. The cushion plate 126 is made of a water-absorbing material to avoid contaminating the inspection table 1 with the liquid drops.

[0028] A method for using an efficient food inspection and analysis reagent adding device includes the following steps: Step 1: The staff quantitatively adds the raw materials of the analysis reagent into the reagent barrel 5, turns on the drive motor 8, and prepares to mix the raw materials.

[0029] Step 2: The driving motor 8 drives the worm 98 to rotate, and the worm 98 meshes with the worm wheel 97, driving the worm wheel 97 and the shaft 95 to rotate. The eccentric wheels 96 at both ends of the shaft 95 drive the two fixed plates 93 to slide back and forth through the opening 94. The connecting plate 91 drives the driving rack 92 to slide and meshes with the transmission gear 65, driving the fixed tube 64 to rotate back and forth. The connecting tube 63 and the reagent barrel 5 rotate back and forth with the fixed tube 64. At the same time, the reagent barrel 5 reciprocates in the vertical direction along the corrugated guide groove 61 through the guide rod 62 to ensure that the raw materials are fully and quickly mixed.

[0030] Step 3: After the reagents are mixed, place the test tube containing the food solvent in the placement port 3 of the placement plate 2, turn on the electric push rod 127, drive the addition tube 11 to slide along the guide port 122 to the top of the test tube through the guide plate 123, turn on the addition pump 10, draw the reagent to the addition pump 10 through the connecting tube 63, the fixed tube 64 and the liquid supply tube 66, and then add it to the test tube quantitatively along the guide tube 13 and the addition tube 11. When the addition tube 11 moves downward, the transmission rod 125 pushes the receiving bucket 124 to rotate to a tilted state to avoid affecting the downward movement of the addition tube 11. After the addition is completed, the electric push rod 127 drives the addition tube 11 to move up and reset, and the transmission rod 125 pulls the receiving bucket 124 to rotate to a horizontal state to receive the droplets at the end of the addition tube 11 to avoid contaminating the inspection table 1.

[0031] Step 4: Turn on the drive motor 8 again, and drive the transmission shaft 99 to rotate through the synchronous belt and the driven wheel. The driving bevel gear 910 is meshed with the driven bevel gear 912, driving the driven bevel gear 912 and the eccentric wheel 911 to rotate. The eccentric wheel 911 pushes the transmission frame 75. With the cooperation of the spring 74, the transmission plate 72 and the support frame 73 slide back and forth along the guide frame 71, so that the test tube reciprocates in the horizontal direction to achieve vibration, thereby ensuring rapid mixing of the reagent and the solvent.

[0032] Step 5: After the test is completed, the placement plate 2 is taken out from the support frame 73, and the positioning rod 78 is moved out of the positioning port 77, and the test tubes can be taken out at one time.

[0033] The specific working principle of the present invention is as follows: In use, first, the staff can quantitatively add the raw materials of the analytical reagent into the reagent barrel 5 and turn on the driving motor 8. When the driving motor 8 is turned on, it can drive the support assembly to operate through the linkage assembly. When the support assembly operates, it can drive the reagent barrel 5 to move in the fixed ring plate 4, so as to fully mix the raw materials in the reagent barrel 5, and then carry out the addition and inspection. After the analytical reagent is mixed, the staff can place the test tube containing the food solvent in the placement opening 3 on the placement plate 2 and place the placement plate 2 through the connection assembly. After the placement is completed, the addition pump 10 can be turned on to quantitatively add the reagent in the reagent barrel 5 into the test tube along the addition tube 11 through the conduit 13. And after the addition is completed, under the action of the anti-pollution structure, the reagent at the port of the addition tube 11 will not drip, avoiding pollution. Subsequently, turning on the driving motor 8 again can drive the connection assembly and the placement plate 2 through the linkage assembly, so that the solvent in the test tube can be quickly mixed with the analytical reagent for inspection. After the inspection is completed, the test tube can be taken out; Specifically, after the raw materials are added to the reagent barrel 5, the drive motor 8 can be turned on. When the drive motor 8 is turned on, the worm 98 can be driven to rotate, and the worm 98 is meshed with the worm wheel 97, thereby driving the worm wheel 97 and the shaft 95 to rotate. When the shaft 95 rotates, the eccentric wheels 96 at both ends are symmetrically arranged. Therefore, when the two eccentric wheels 96 rotate, they can drive the two fixed plates 93 to slide back and forth in turn through the opening 94, thereby driving the drive rack 92 to slide through the connecting plate 91, and the drive rack 92 is meshed with the transmission gear 65, and the shaft 95 rotates. And it can drive the fixed tube 64 to reciprocate. At the same time, during the reciprocating rotation of the fixed tube 64, the connecting tube 63 is slidably connected to the fixed tube 64, so the connecting tube 63 and the reagent barrel 5 can reciprocate with the fixed tube 64. During the reciprocating rotation of the reagent barrel 5, the guide rod 62 on the outer wall thereof can slide along the corrugated guide groove 61 on the inner wall of the fixed ring plate 4, so that the reagent barrel 5 can be driven to reciprocate in the vertical direction. With the reciprocating rotation of the reagent barrel 5, it is ensured that the raw materials in the reagent barrel 5 can be fully and quickly mixed evenly. After the reagents in the reagent barrel 5 are mixed and the test tubes are placed, the electric push rod 127 can be opened to drive the plurality of adding tubes 11 to slide along the guide opening 122 through the guide plate 123, so that the adding tubes 11 move downward, and then the adding pump 10 is opened to pump the reagents in the reagent barrel 5 into the adding pump 10 through the connecting pipe 63, the fixed pipe 64 and the liquid supply pipe 66, and the reagents can be quantitatively added to the test tubes along the guide tube 13 and the adding tube 11. In the process of the adding tube 11 moving downward, the receiving bucket 11 can be driven by the transmission rod 125. 24 is pushed to make the receiving bucket 124 rotate from a horizontal state to an inclined state, so as to avoid affecting the normal downward movement of the addition tube 11. When the reagent is added, the electric push rod 127 drives the addition tube 11 to move upward and reset, and the receiving bucket 124 can be pulled by the transmission rod 125, so that the receiving bucket 124 rotates to a horizontal state and is located directly below the addition tube 11. The liquid droplets at the port of the addition tube 11 can drip onto the pad 126 in the receiving bucket 124. The pad 126 is made of a water-absorbing material to prevent the liquid droplets from contaminating the test bench 1; After the reagent is added, the staff can start the driving motor 8 again and drive the transmission shaft 99 to rotate through the synchronous belt and the driven wheel. The driving bevel gear 910 is meshed with the driven bevel gear 912, and then the driven bevel gear 912 and the eccentric wheel 911 can be driven to rotate. During the rotation of the eccentric wheel 911, the transmission frame 75 can be pushed. With the cooperation of the spring 74, the transmission plate 72 and the support frame 73 can slide back and forth along the guide frame 71, so that the test tube on the placement plate 2 can reciprocate horizontally to achieve vibration, ensuring that the reagent and the solvent can be quickly mixed for testing. After the test is completed, the placement plate 2 can be taken out of the support frame 73, and the positioning rod 78 can be moved out of the positioning port 77, so that the test tube can be taken out at one time, which is more convenient.
